TypeSpec is great, but if you're working with Rust and you're about to write a new project that will require an OpenApi spec sooner or later, I'd like to recommend a web framework that has spec generation baked in:
All you need to do is derive a trait on your response structs and in return you get an almost perfectly generated spec. Unions, objects, enums are first class citizens.
Also, if you're from coming from PHP, the controllers feel very much like symfony controllers.
P.s. Please do recommend an ORM that would feel closer to doctrine. I miss doctrine.
